Title: Fast idle device for internal-combustion engine
Inventor: KOBAYASHI KAZUYUKI
IPC: F02D9/02
Filed: 1985-03-12
Abstract: PURPOSE:To form a control mechanism opening a throttle valve in low temperature while closing it in high temperature, by manufacturing a member, which restricts a closing position of the throttle valve, by a high molecular resin material with its elastic coefficient decreasing at a predetermined temperature or more. CONSTITUTION:A throttle valve 4 is continually urged in its closing direction by governor force or valve closing force through a rod 6 and a throttle lever 3. One end of the throttle lever 3 is adapted to a leaf spring 11, a its maximum flexing position is restricted by a bolt 5. The leaf spring 11 is manufactured by high molecular resin of urethane elastomer or the like polymerizing, for instance, isofluondiisocyanate and bisphenil, and the leaf spring, softening in high temperature to decrease its elastic coefficient, flexes as shown in the drawing, enabling the throttle valve 4 to be closes to an opening restricted by the bolt 5. The leaf spring 11, having high elasticity in low temperature, overcomes the valve closing force to open the throttle valve 4 to the predetermined opening.

Filed: 1983-03-23
Abstract: PURPOSE:To make high-precision and high-speed flaw detection possible by generating and detecting plate waves with one electromagnetic ultrasonic transducer to detect flaws surely throughout all of the region. CONSTITUTION:A DC power source 12 is turned on to excite an electromagnet 8a with DC, and a vertical static magnetic field B0 is given to the surface of a sample plate body 1. A discriminator 11 sends a control signal to a pulser 10a to drive it and supplies pulse radio waves to an oscillation generating and detecting coil 8b. At this time, eddy currents J1-J4 which change the direction alternately are induced, and a Lorentz force F is generated by the interaction with the static magnetic field B0. Then, the sample plate body 1 is expanded and contracted to generate plate waves indicated by broken lines. Plate waves 13 are reflected on the end face or a defective part of the plate body 1 and are returned to oscillate again the part of a transducer 8 facing this end face or the defective part. The detection signal induced in the coil 8b is processed by a receiver in a pulser receiver 10, and a discriminator 11 discriminates properties of the plate body 1 on a basis of this signal. Thus, high-speed flaw detection is possible, and a high S/N is obtained.

IPC: G02B6/36
Filed: 1989-02-28
Abstract: PURPOSE:To enhance the utilization efficiency of light by providing a corrugated ruggedness on the inner side face of a tubular external inserting member or the outer side face of a light transmitting member. CONSTITUTION:The 1st tubular member 1 having light transmission ability is fixed on the 2nd tubular outer peripheral member 2 so that the end parts are arranged on the same axis, and the corrugated ruggedness 3 is provided on the inner side part of the member 2.

Filed: 1985-03-12
Abstract: PURPOSE:To obtain a sensor which is stable against the variation of a transmission characteristic, and convenient for handling, by providing a polarizing device, a 1/4 wavelength plate, and a reflecting plate. CONSTITUTION:The rays of light which are emitted from a light source 1 are converted to a linearly polarized light having an inclination of 45 deg. against the intrinsic polarizing axis of a polarization plane maintaining optical fiber 3 by a polarization separating type polarizer 23, and made incident on the polarization plane maintaining optical fiber 3. As for the polarization plane maintaining optical fiber 3, the propagation constant is different in the X axis direction and the Y axis direction in the intrinsic polarizing axis, and the components of the X axis direction and the Y axis direction of an incident linearly polarized light are propagated in the polarization plane maintaining optical fiber 3 as each separate linearly polarized wave. This light is further converted to each circularly polarized light by a 1/4 wavelength plate 4, and reflected by a reflecting plate 6 through a Faraday element 5. The reflected and returned light becomes a circularly polarized light which goes round in reverse to the time of an incidence, and it is converted to a linearly polarized light by the 1/4 wavelength plate 4 and returned through the inside of the polarization plane maintaining optical fiber 3. This light is separated by the polarization separating type polarizer 23 and detected by a photodetector 7.

Title: Rotary body and regulation method for dynamic unbalance thereof
Inventor: NISHIHARA YASUHIRO
IPC: G11B19/20
Filed: 1989-03-01
Abstract: PURPOSE:To facilitate secondary microadjustment control of a balance weight by a method wherein the given number of balance weights are disposed with a time in positions in a plurality of concentric recessed and protrusion parts, having difference radii, on the center of a rotary shaft and formed on the upper surface of a rotary body. CONSTITUTION:A dynamic unbalance is regulated as a test by a dynamic unbalance tester is applied on a rotary body 1. When a dynamic unbalance position is detected, a proper weight of a balance weight 5 is disposed in the dynamic unbalance position of an outer annular recessed part 2a. When the rotary body 1 is set to the dynamic unbalance tester again for rotation, it is detected that a dynamic unbalance is eliminated or a slight one remains. In order to remove an unbalance, a different balance weight 6 is disposed in a position in an inner annular recessed part. In which case, with the decrease in a distance to the inner annular recessed part from the rotary shaft compared with that to an outer annular recessed part 2a therefrom, the weight of a balance weight can be increased to a high value. Namely, microadjustment control is always heretofore difficult to make, but by increasing the weight of the balance weight 6 to a high value, a dynamic unbalance can be high-efficiently regulated by means of a total weight obtained by adding it to the already- arranged balance weight 5.

Abstract: PURPOSE:To lessen a load of a calculator for calculating a pulse interval across a plurality of external pulses. CONSTITUTION:An external pulse detector 1 detects a rise of an external pulse CK at each time of inputting it, and outputs a detection signal SA to a counter 2. The counter 2 counts the signal SA. A frequency set register 3 sets a predetermined number N for calculating the interval of predetermined number N of the generated pulses CK. A comparator 4 compares a counted value NA with the number N, and outputs a control signal SB in the case of coincidence. The signal SB is output to the counter 2 and an interrupt signal generator 5. The counter 2 resets the counted value NA in response to the signal SB. An interrupt signal generator 5 outputs an interrupt signal SC for calculating the interval of the number N of the pulses CK in response to the signal SB. A transfer circuit 6 reads a time when a timer 7 counts in response to the signal SC, and transfers it to a time storage register 8.
